Why can't plants support their own weight?
Plants are not able to support their own weight because they don't have an internal skeleton like animals do. Instead, they rely on external support structures like the cell wall, interlocking branches and roots, and external support from other plants or structures. Plants also lack muscles and therefore the ability to actively move and contract to support their own weight. The main reasons why plants can't support their own weight are: No internal skeleton Reliance on external support Lack of musclesWithout these key components, plants are unable to develop the strength and resilience to support their own weight.
